Title: Preparation of hydrolysed zirconium salt precursors and high purity zirconia.
Inventor: HOUCHIN MARTIN RICHARD
IPC: C22B34/14
Filed: 1987-06-05
Abstract: In the economic production of hydrolysed zirconiferous precipitate, hydrolysis is carried out by the addition of base to aqueous acidic zirconium sulphate solution, to lower the H<+> to and maintain within a pH range of 3 to 7, preferably within 4 to 6. The base may be selected from ammonia, basic ammonium salts, e.g., ammonia-buffered ammonium salts, an alkali metal hydroxide, carbonate or bicarbonate. Specific bases include ammonia and ammonium/sodium/potassium hydroxide, carbonate or bicarbonate, with particular preference for ammonia and ammonium/sodium hydroxide. The starting materials may be incorporated in batchwise or continuous fashion, batchwise by combining them in a body of water, suitable electrolyte or solvent with thorough continuous mixing or continuously by mixing them together in a flowing stream. An additive in the form of an inorganic stabiliser or an organic surfactant may also be included. Inorganic stabilisers may be selected from one or more of Y2O3, Ce2O3, Al2O3, MgO and CaO or precursors thereof. In the finishing stage, either further base may be added to lower residual sulphate content or acid added to remove acid-soluble impurities. The precipitated product is then separated, (e.g., by filtration), washed and calcined to give pure zirconia. High purity zirconia has particular application in the electronics industry and for the production of partially stabilised zirconia ceramics.

Inventor: KUSUMI MIYOKO
IPC: C12Q1/28
Filed: 1988-04-28
Abstract: A luminol serving as a luminescent reagent is caused to react with a catalase or an immobilized catalase in order to decompose hydrogen peroxide therein. When the catalase is used, the catalase is removed from the reagent, or the reaction between the catalase and the hydrogen peroxide of the reagent is stopped by adding an inhibitor, such as sodium azide, thereto. When the concentration of the catalase is previously adjusted to be 10 to 200 U/ml, it is not required to remove the catalase from the reagent and to cause the reaction between the catalase and the hydrogen peroxide of the reagent to be stopped. This reagent is mixed with a hydrogen peroxide to be tested and a catalyst, and the quantity of light produced by the reaction between the reagent and the hydrogen peroxide is measured. The content of the hydrogen peroxide is determined on the basis of the quantity of light produced.

Abstract: The module for a stack of discs of a magnetic disc player has data discs (30) separated from one another by spacer rings (31) on a hub (5) arranged rotatably in a housing (4). The said discs are pushed against a radially projecting, elastically deformable flange (52) of the hub and are also frictionally braced by means of a tensioning plate (10). A tensioning ring (9) is provided and, as receiver for the tensioning plate (10), is fixed on the end face (54) of the hub facing away from the flange. The tensioning ring is also designed in such a way that it deforms reversibly under material stresses occurring as a result of changes in temperature. Due to this twisting deformation of the tensioning ring, different thermal dilations of the hub or elements pushed onto it are absorbed and compensated in interaction with the deformation of the hub flange.

Inventor: LENZ MICHAEL DIPL-ING FH
IPC: H03K17/66
Filed: 1988-10-10
Abstract: In order to suppress cross-currents (cross-conductor currents) in push-pull stages, which generate high power losses and can lead to destruction of the output transistors (T1, T2), mutually associated signal flanks of the triggering push-pull signals (U1, U2) must follow one another separated in time. In order to minimise the dead times which occur and at the same time to become independent of parameter fluctuations of the circuit elements, the invention proposes that the output current of the respectively conducting output transistor (T1, T2) be detected and that the triggering signal for the complementary output transistor (T2, T1) not be released until a switch-off criterion is met.
